This is different from most media players, as\n * audio is more often used as the primary timing source. For the foreseeable future, VHS\n * will continue to use video as the primary timing source, due to the current logic and\n * expectations built around it.\n\n * Since the timing follows video, in order to maintain sync, the video loader is\n * responsible for setting both audio and video source buffer timestamp offsets.\n *\n * Setting different values for audio and video source buffers could lead to\n * desyncing. The following examples demonstrate some of the situations where this\n * distinction is important. Note that all of these cases involve demuxed content. When\n * content is muxed, the audio and video are packaged together, therefore syncing\n * separate media playlists is not an issue.\n *\n * CASE 1: Audio prepares to load a new timeline before video:\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:                     ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader              ^\n *\n * In the above example, the audio loader is preparing to load the 6th segment, the first\n * after a discontinuity, while the video loader is still loading the 5th segment, before\n * the discontinuity.\n *\n * If the audio loader goes ahead and loads and appends the 6th segment before the video\n * loader crosses the discontinuity, then when appended, the 6th audio segment will use\n * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,\n * the audio loader must provide the audioAppendStart value to trim the content in the\n * transmuxer, and that value relies on the audio timestamp offset. Since the audio\n * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the\n * segment until that value is provided.\n *\n * CASE 2: Video prepares to load a new timeline before audio:\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:             ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader                      ^\n *\n * In the above example, the video loader is preparing to load the 6th segment, the first\n * after a discontinuity, while the audio loader is still loading the 5th segment, before\n * the discontinuity.\n *\n * If the video loader goes ahead and loads and appends the 6th segment, then once the\n * segment is loaded and processed, both the video and audio timestamp offsets will be\n * set, since video is used as the primary timing source. This is to ensure content lines\n * up appropriately, as any modifications to the video timing are reflected by audio when\n * the video loader sets the audio and video timestamp offsets to the same value. However,\n * setting the timestamp offset for audio before audio has had a chance to change\n * timelines will likely lead to desyncing, as the audio loader will append segment 5 with\n * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.\n *\n * CASE 3: When seeking, audio prepares to load a new timeline before video\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:           ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader            ^\n *\n * In the above example, both audio and video loaders are loading segments from timeline\n * 0, but imagine that the seek originated from timeline 1.\n *\n * When seeking to a new timeline, the timestamp offset will be set based on the expected\n * segment start of the loaded video segment. In order to maintain sync, the audio loader\n * must wait for the video loader to load its segment and update both the audio and video\n * timestamp offsets before it may load and append its own segment. This is the case\n * whether the seek results in a mismatched segment request (e.g., the audio loader\n * chooses to load segment 3 and the video loader chooses to load segment 4) or the\n * loaders choose to load the same segment index from each playlist, as the segments may\n * not be aligned perfectly, even for matching segment indexes.\n *\n * @param {Object} timelinechangeController\n * @param {number} currentTimeline\n *        The timeline currently being followed by the loader\n * @param {number} segmentTimeline\n *        The timeline of the segment being loaded\n * @param {('main'|'audio')} loaderType\n *        The loader type\n * @param {boolean} audioDisabled\n *        Whether the audio is disabled for the loader.

If audio and video streams are not perfectly in-sync, then\n      //    the mapping will be off for one of the streams, dependent on which one was\n      //    first saved (see (1)).\n      // 3) Primary timing goes by video in VHS, so the mapping should be video.\n      //\n      // Since the audio loader will wait for the main loader to load the first segment,\n      // the main loader will save the first timeline mapping, and ensure that there won't\n      // be a case where audio loads two segments without saving a mapping (thus leading\n      // to missing segment timing info).\n      this.syncController_.saveSegmentTimingInfo({\n        segmentInfo,\n        shouldSaveTimelineMapping: this.loaderType_ === 'main'\n      });\n    }\n    const segmentDurationMessage = getTroublesomeSegmentDurationMessage(segmentInfo, this.sourceType_);\n    if (segmentDurationMessage) {\n      if (segmentDurationMessage.severity === 'warn') {\n        videojs.log.warn(segmentDurationMessage.message);\n      } else {\n        this.logger_(segmentDurationMessage.message);\n      }\n    }\n    this.recordThroughput_(segmentInfo);\n    this.pendingSegment_ = null;\n    this.state = 'READY';\n    if (segmentInfo.isSyncRequest) {\n      this.trigger('syncinfoupdate'); // if the sync request was not appended\n      // then it was not the correct segment.\n      // throw it away and use the data it gave us\n      // to get the correct one.\n\n      if (!segmentInfo.hasAppendedData_) {\n        this.logger_(`Throwing away un-appended sync request ${segmentInfoString(segmentInfo)}`);\n        return;\n      }\n    }\n    this.logger_(`Appended ${segmentInfoString(segmentInfo)}`);\n    this.addSegmentMetadataCue_(segmentInfo);\n    this.fetchAtBuffer_ = true;\n    if (this.currentTimeline_ !== segmentInfo.timeline) {\n      this.timelineChangeController_.lastTimelineChange({\n        type: this.loaderType_,\n        from: this.currentTimeline_,\n        to: segmentInfo.timeline\n      }); // If audio is not disabled, the main segment loader is responsible for updating\n      // the audio timeline as well.

The\n  primary way of interacting with a promise is through its `then` method, which\n  registers callbacks to receive either a promise\'s eventual value or the reason\n  why the promise cannot be fulfilled.\n\n  Terminology\n  -----------\n\n  - `promise` is an object or function with a `then` method whose behavior conforms to this specification.\n  - `thenable` is an object or function that defines a `then` method.\n  - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).\n  - `exception` is a value that is thrown using the throw statement.\n  - `reason` is a value that indicates why a promise was rejected.\n  - `settled` the final resting state of a promise, fulfilled or rejected.\n\n  A promise can be in one of three states: pending, fulfilled, or rejected.\n\n  Promises that are fulfilled have a fulfillment value and are in the fulfilled\n  state.  Promises that are rejected have a rejection reason and are in the\n  rejected state.  A fulfillment value is never a thenable.\n\n  Promises can also be said to *resolve* a value.  If this value is also a\n  promise, then the original promise\'s settled state will match the value\'s\n  settled state.  So a promise that *resolves* a promise that rejects will\n  itself reject, and a promise that *resolves* a promise that fulfills will\n  itself fulfill.\n\n\n  Basic Usage:\n  ------------\n\n  ```js\n  let promise = new Promise(function(resolve, reject) {\n    // on success\n    resolve(value);\n\n    // on failure\n    reject(reason);\n  });\n\n  promise.then(function(value) {\n    // on fulfillment\n  }, function(reason) {\n    // on rejection\n  });\n  ```\n\n  Advanced Usage:\n  ---------------\n\n  Promises shine when abstracting away asynchronous interactions such as\n  `XMLHttpRequest`s.\n\n  ```js\n  function getJSON(url) {\n    return new Promise(function(resolve, reject){\n      let xhr = new XMLHttpRequest();\n\n      xhr.open(\'GET\', url);\n      xhr.onreadystatechange = handler;\n      xhr.responseType = \'json\';\n      xhr.setRequestHeader(\'Accept\', \'application/json\');\n      xhr.send();\n\n      function handler() {\n        if (this.readyState === this.DONE) {\n          if (this.status === 200) {\n            resolve(this.response);\n          } else {\n            reject(new Error(\'getJSON: `\' + url + \'` failed with status: [\' + this.status + \']\'));\n          }\n        }\n      };\n    });\n  }\n\n  getJSON(\'/posts.json\').then(function(json) {\n    // on fulfillment\n  }, function(reason) {\n    // on rejection\n  });\n  ```\n\n  Unlike callbacks, promises are great composable primitives.\n\n  ```js\n  Promise.all([\n    getJSON(\'/posts\'),\n    getJSON(\'/comments\')\n  ]).then(function(values){\n    values[0] // => postsJSON\n    values[1] // => commentsJSON\n\n    return values;\n  });\n  ```\n\n  @class Promise\n  @param {Function} resolver\n  Useful for tooling.\n  @constructor\n*/\n\nvar Promise$1 = function () {\n  function Promise(resolver) {\n    this[PROMISE_ID] = nextId();\n    this._result = this._state = undefined;\n    this._subscribers = [];\n\n    if (noop !== resolver) {\n      typeof resolver !== \'function\' && needsResolver();\n      this instanceof Promise ? initializePromise(this, resolver) : needsNew();\n    }\n  }\n\n  /**\n  The primary way of interacting with a promise is through its `then` method,\n  which registers callbacks to receive either a promise\'s eventual value or the\n  reason why the promise cannot be fulfilled.\n   ```js\n  findUser().then(function(user){\n    // user is available\n  }, function(reason){\n    // user is unavailable, and you are given the reason why\n  });\n  ```\n   Chaining\n  --------\n   The return value of `then` is itself a promise.  This second, \'downstream\'\n  promise is resolved with the return value of the first promise\'s fulfillment\n  or rejection handler, or rejected if the handler throws an exception.\n   ```js\n  findUser().then(function (user) {\n    return user.name;\n  }, function (reason) {\n    return \'default name\';\n  }).then(function (userName) {\n    // If `findUser` fulfilled, `userName` will be the user\'s name, otherwise it\n    // will be `\'default name\'`\n  });\n   findUser().then(function (user) {\n    throw new Error(\'Found user, but still unhappy\');\n  }, function (reason) {\n    throw new Error(\'`findUser` rejected and we\'re unhappy\');\n  }).then(function (value) {\n    // never reached\n  }, function (reason) {\n    // if `findUser` fulfilled, `reason` will be \'Found user, but still unhappy\'.\n    // If `findUser` rejected, `reason` will be \'`findUser` rejected and we\'re unhappy\'.\n  });\n  ```\n  If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.\n   ```js\n  findUser().then(function (user) {\n    throw new PedagogicalException(\'Upstream error\');\n  }).then(function (value) {\n    // never reached\n  }).then(function (value) {\n    // never reached\n  }, function (reason) {\n    // The `PedgagocialException` is propagated all the way down to here\n  });\n  ```\n   Assimilation\n  ------------\n   Sometimes the value you want to propagate to a downstream promise can only be\n  retrieved asynchronously. This can be achieved by returning a promise in the\n  fulfillment or rejection handler. The downstream promise will then be pending\n  until the returned promise is settled. This is called *assimilation*.\n   ```js\n  findUser().then(function (user) {\n    return findCommentsByAuthor(user);\n  }).then(function (comments) {\n    // The user\'s comments are now available\n  });\n  ```\n   If the assimliated promise rejects, then the downstream promise will also reject.\n   ```js\n  findUser().then(function (user) {\n    return findCommentsByAuthor(user);\n  }).then(function (comments) {\n    // If `findCommentsByAuthor` fulfills, we\'ll have the value here\n  }, function (reason) {\n    // If `findCommentsByAuthor` rejects, we\'ll have the reason here\n  });\n  ```\n   Simple Example\n  --------------\n   Synchronous Example\n   ```javascript\n  let result;\n   try {\n    result = findResult();\n    // success\n  } catch(reason) {\n    // failure\n  }\n  ```\n   Errback Example\n   ```js\n  findResult(function(result, err){\n    if (err) {\n      // failure\n    } else {\n      // success\n    }\n  });\n  ```\n   Promise Example;\n   ```javascript\n  findResult().then(function(result){\n    // success\n  }, function(reason){\n    // failure\n  });\n  ```\n   Advanced Example\n  --------------\n   Synchronous Example\n   ```javascript\n  let author, books;\n   try {\n    author = findAuthor();\n    books  = findBooksByAuthor(author);\n    // success\n  } catch(reason) {\n    // failure\n  }\n  ```\n   Errback Example\n   ```js\n   function foundBooks(books) {\n   }\n   function failure(reason) {\n   }\n   findAuthor(function(author, err){\n    if (err) {\n      failure(err);\n      // failure\n    } else {\n      try {\n        findBoooksByAuthor(author, function(books, err) {\n          if (err) {\n            failure(err);\n          } else {\n            try {\n              foundBooks(books);\n            } catch(reason) {\n              failure(reason);\n            }\n          }\n        });\n      } catch(error) {\n        failure(err);\n      }\n      // success\n    }\n  });\n  ```\n   Promise Example;\n   ```javascript\n  findAuthor().\n    then(findBooksByAuthor).\n    then(function(books){\n      // found books\n  }).catch(function(reason){\n    // something went wrong\n  });\n  ```\n   @method then\n  @param {Function} onFulfilled\n  @param {Function} onRejected\n  Useful for tooling.\n  @return {Promise}\n  */\n\n  /**\n  `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same\n  as the catch block of a try/catch statement.\n  ```js\n  function findAuthor(){\n  throw new Error(\'couldn\'t find that author\');\n  }\n  // synchronous\n  try {\n  findAuthor();\n  } catch(reason) {\n  // something went wrong\n  }\n  // async with promises\n  findAuthor().catch(function(reason){\n  // something went wrong\n  });\n  ```\n  @method catch\n  @param {Function} onRejection\n  Useful for tooling.\n  @return {Promise}\n  */\n\n\n  Promise.prototype.catch = function _catch(onRejection) {\n    return this.then(null, onRejection);\n  };\n\n  /**\n    `finally` will be invoked regardless of the promise\'s fate just as native\n    try/catch/finally behaves\n  \n    Synchronous example:\n  \n    ```js\n    findAuthor() {\n      if (Math.random() > 0.5) {\n        throw new Error();\n      }\n      return new Author();\n    }\n  \n    try {\n      return findAuthor();

Sometimes it\'s called a "filter",\n// but that\'s not a great name for it, since that implies a thing where\n// some bits pass through, and others are simply ignored.  (That would\n// be a valid example of a transform, of course.)\n//\n// While the output is causally related to the input, it\'s not a\n// necessarily symmetric or synchronous transformation.  For example,\n// a zlib stream might take multiple plain-text writes(), and then\n// emit a single compressed chunk some time in the future.\n//\n// Here\'s how this works:\n//\n// The Transform stream has all the aspects of the readable and writable\n// stream classes.  When you write(chunk), that calls _write(chunk,cb)\n// internally, and returns false if there\'s a lot of pending writes\n// buffered up.  When you call read(), that calls _read(n) until\n// there\'s enough pending readable data buffered up.\n//\n// In a transform stream, the written data is placed in a buffer.  When\n// _read(n) is called, it transforms the queued up data, calling the\n// buffered _write cb\'s as it consumes chunks.  If consuming a single\n// written chunk would result in multiple output chunks, then the first\n// outputted bit calls the readcb, and subsequent chunks just go into\n// the read buffer, and will cause it to emit \'readable\' if necessary.\n//\n// This way, back-pressure is actually determined by the reading side,\n// since _read has to be called to start processing a new chunk.  However,\n// a pathological inflate type of transform can cause excessive buffering\n// here.  For example, imagine a stream where every byte of input is\n// interpreted as an integer from 0-255, and then results in that many\n// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in\n// 1kb of data being output.  In this case, you could write a very small\n// amount of input, and end up with a very large amount of output.  In\n// such a pathological inflating mechanism, there\'d be no way to tell\n// the system to stop doing the transform.  A single 4MB write could\n// cause the system to run out of memory.\n//\n// However, even in such a pathological case, only a single written chunk\n// would be consumed, and then the rest would wait (un-transformed) until\n// the results of the previous transformed chunk were consumed.\n\n\n\nmodule.exports = Transform;\n\nvar Duplex = __nested_webpack_require_411682__(/*! ./_stream_duplex */ "./node_modules/readable-stream/lib/_stream_duplex.js");\n\n/*<replacement>*/\nvar util = __nested_webpack_require_411682__(/*! core-util-is */ "./node_modules/core-util-is/lib/util.js");\nutil.inherits = __nested_webpack_require_411682__(/*! inherits */ "./node_modules/inherits/inherits_browser.js");\n/*</replacement>*/\n\nutil.inherits(Transform, Duplex);\n\nfunction afterTransform(er, data) {\n  var ts = this._transformState;\n  ts.transforming = false;\n\n  var cb = ts.writecb;\n\n  if (!cb) {\n    return this.emit(\'error\', new Error(\'write callback called multiple times\'));\n  }\n\n  ts.writechunk = null;\n  ts.writecb = null;\n\n  if (data != null) // single equals check for both `null` and `undefined`\n    this.push(data);\n\n  cb(er);\n\n  var rs = this._readableState;\n  rs.reading = false;\n  if (rs.needReadable || rs.length < rs.highWaterMark) {\n    this._read(rs.highWaterMark);\n  }\n}\n\nfunction Transform(options) {\n  if (!(this instanceof Transform)) return new Transform(options);\n\n  Duplex.call(this, options);\n\n  this._transformState = {\n    afterTransform: afterTransform.bind(this),\n    needTransform: false,\n    transforming: false,\n    writecb: null,\n    writechunk: null,\n    writeencoding: null\n  };\n\n  // start out asking for a readable event once data is transformed.\n  this._readableState.needReadable = true;\n\n  // we have implemented the _read method, and done the other things\n  // that Readable wants before the first _read call, so unset the\n  // sync guard flag.\n  this._readableState.sync = false;\n\n  if (options) {\n    if (typeof options.transform === \'function\') this._transform = options.transform;\n\n    if (typeof options.flush === \'function\') this._flush = options.flush;\n  }\n\n  // When the writable side finishes, then flush out anything remaining.\n  this.on(\'prefinish\', prefinish);\n}\n\nfunction prefinish() {\n  var _this = this;\n\n  if (typeof this._flush === \'function\') {\n    this._flush(function (er, data) {\n      done(_this, er, data);\n    });\n  } else {\n    done(this, null, null);\n  }\n}\n\nTransform.prototype.push = function (chunk, encoding) {\n  this._transformState.needTransform = false;\n  return Duplex.prototype.push.call(this, chunk, encoding);\n};\n\n// This is the part where you do stuff!\n// override this function in implementation classes.\n// \'chunk\' is an input chunk.\n//\n// Call `push(newChunk)` to pass along transformed output\n// to the readable side.

The following examples demonstrate some of the situations where this\n * distinction is important. Note that all of these cases involve demuxed content. When\n * content is muxed, the audio and video are packaged together, therefore syncing\n * separate media playlists is not an issue.\n *\n * CASE 1: Audio prepares to load a new timeline before video:\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:                     ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader              ^\n *\n * In the above example, the audio loader is preparing to load the 6th segment, the first\n * after a discontinuity, while the video loader is still loading the 5th segment, before\n * the discontinuity.\n *\n * If the audio loader goes ahead and loads and appends the 6th segment before the video\n * loader crosses the discontinuity, then when appended, the 6th audio segment will use\n * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,\n * the audio loader must provide the audioAppendStart value to trim the content in the\n * transmuxer, and that value relies on the audio timestamp offset. Since the audio\n * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the\n * segment until that value is provided.\n *\n * CASE 2: Video prepares to load a new timeline before audio:\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:             ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader                      ^\n *\n * In the above example, the video loader is preparing to load the 6th segment, the first\n * after a discontinuity, while the audio loader is still loading the 5th segment, before\n * the discontinuity.\n *\n * If the video loader goes ahead and loads and appends the 6th segment, then once the\n * segment is loaded and processed, both the video and audio timestamp offsets will be\n * set, since video is used as the primary timing source. This is to ensure content lines\n * up appropriately, as any modifications to the video timing are reflected by audio when\n * the video loader sets the audio and video timestamp offsets to the same value. However,\n * setting the timestamp offset for audio before audio has had a chance to change\n * timelines will likely lead to desyncing, as the audio loader will append segment 5 with\n * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.\n *\n * CASE 3: When seeking, audio prepares to load a new timeline before video\n *\n * Timeline:       0                 1\n * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Audio Loader:           ^\n * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9\n * Video Loader            ^\n *\n * In the above example, both audio and video loaders are loading segments from timeline\n * 0, but imagine that the seek originated from timeline 1.\n *\n * When seeking to a new timeline, the timestamp offset will be set based on the expected\n * segment start of the loaded video segment. In order to maintain sync, the audio loader\n * must wait for the video loader to load its segment and update both the audio and video\n * timestamp offsets before it may load and append its own segment. This is the case\n * whether the seek results in a mismatched segment request (e.g., the audio loader\n * chooses to load segment 3 and the video loader chooses to load segment 4) or the\n * loaders choose to load the same segment index from each playlist, as the segments may\n * not be aligned perfectly, even for matching segment indexes.\n *\n * @param {Object} timelinechangeController\n * @param {number} currentTimeline\n *        The timeline currently being followed by the loader\n * @param {number} segmentTimeline\n *        The timeline of the segment being loaded\n * @param {('main'|'audio')} loaderType\n *        The loader type\n * @param {boolean} audioDisabled\n *        Whether the audio is disabled for the loader.

Functions\n// ----------------\n// Our most fundamental functions operate on any JavaScript object.\n// Most functions in Underscore depend on at least one function in this section.\n\n// A group of
